Thank you for your kind response.

In order to correct perspective, both vertically and horizontally, there is an app for mobile phones and tablets which is call Snapseed. Its tool for correcting that works very well.

Another way is to use Photoshop or Lightroom, both have good good tools for that as well. But way needs to learn a bit, thats means time.

A lot of tutorials in youtube about this aspect, just search for 'correcting perspective in digital photography'
